First notebook entry: Introducing myself

Hello! My name is Lena. I want to learn the English and Spanish languages. I can teach you the Russian language in Skype or ICQ. I am a very sociable girl.

Hi Lena! You need to add the articles when you have the noun being modified by an adjective which preceeds the noun. In other words, if you had said "I want to learn English and Spanish", you don't need to use "the" because in that case "English" and "Spanish" are nouns which are not being modified by adjectives as was the noun "languages" in your original sentence.

You could also say "I am very sociable" and not need the article "a".
